To all wlom 'it may concern: l

Be it known that I, EDWIN- N., P anBLne citizen of the United States, residng Bet er-im in the county ofEsseX and'Stete.

and useful Improvements in- Sole-Pressing:

Machines; and, I do hereby deela re the fellowing to be a full, clear, and emet cleseription of the* inirention, `such :is: Willem-tile others skilled in the art to which it upper* tziins to. make anduse the same. i

The present ,inve'ntion reletes te Sele-'press inje' machines, and more pa-rticul'erly .to ma reasonshoweve', there, is a tendency for the edge of the sole to move 'out of contaet ith the-gagebefore rt'is clen ped n-poston,

vention contemplates the provision in a mzichine of this type having upper and lower terms, of a gripping device for' dumping theflat ing a sole engaging surface arrunged to register with a coperating recess forned in one ef the, terms' to present a smooth, substentiallly unbroken pressing surface to' the Sele When the forms are in a 'position of pressure.,

Fig. 3 is a detail illustreting the nornal positienef the grippng member prior to porting form'.

The illustrnted embodinent of the ihVen-d tion is shown in connectionwith a machine of 'thetype descrbed and `illustrated in' zi copending* application. of the'inventor, Serial spring 5 V and 'is' caused to move'downwardly With i the heel: end of Wfll'd 'motement of s moveclinto and out of engagement ith ;The sole is positioned upen the supportingorm l'by a," heel gaige iwhich is normally held in positien tbove the surface of the" form ;by e i sole to` a supporting form and. hLV- the sole by the' downthe gripping der ice.

(Ihe grippingwdeVice is tulcrumed at Tand the sole by a rol l' 8 engaging With the upper surface of' the gripper nrm 9 rolling thereoveres the lower form is moved' horizonta l ly toand froma position :of cleeranceu Inspring heel' soles' theheellift'is 21ttached prier to the -molding operation 'and r it. is therefere Very desirabl'eto; properly pe sition and clamp the soie upon the support ing form without merring or otherwise inuri ng* the 'surfaee ofthesoie.` To ths end,

the g'ripping device of the present invention is provided with a sole engaging surface registering eXactly with a recess formed in the 'pressing form so that'when the two forms are in pressing position a smooth, substantially unbroken pressing surface is presented to the work to mold the soie without marring the surface. Thegripper arm 9 is provided with an upstanding projection 18 forned integrai therewith 'and received;

12 forined integral therewith which supports a forwardly extending arm 1 1 upon the outer end of which a gripping member 15 iscarried. The arm 14: 'is slidingiy sup-` ported upon the member 12 by coperating ways formed upon the arm and member and the arm is clamped in any adjusted pcsition by a ciamping bolt 17 threadedly nounted in the member 12 and passing through a slot formed in the arm14c. The gripping member 15 is provided with 'a lug in the bifurcated outer end l of the arm 14, the two being pivotaliy connected by a bolt 19. The upper form 2 is provided with the usual slot 20 to receive the gripper arm,

and in addition, a shallow recess 21 is provided -in the pressing face of the form which shaii force thef heel end of the sole into contact' with the gage and retain the soie Gomes of this iatent may be obtai ed for p gether.

It will be noted from aninspection of Fig. 1 that in this type of sole a sharp break is v formed at the shank, which break shortens the sole and tends todraw the twoends to- In order to properly position the sole it sfdesirable that the gripping device in this position during :the pressing ,operation; Tothis end, `the sole engaging surface ofthe grppmg member 15 is 'normaliypostoned at an angle to the sole, as'shown clearly in ;FigL 3 and when the gripp'ing member is moved -downwardly to clamp 'the' sole t'o. the form, the soleengaging surface "ofthe 'member is .turned into a position parallel to the surface of the so-le', which turningmovement causes a longitudinal move' ment ofthe sole engaging surface toward f the heelgage, forcing the sole into contact' with'the gage. To this'end, ithe lug 18 has a flat spring23 attached thereto by screws ,l 24:,.the spring hav ng its upper end bent to.

/Vhen the grip'ping member is depressed to ciamp the solein position, the rear' portion of the face first 'engages with the heei end of the sole, and as :the gripping member' then forces' the sole into engagement with the form, the member is moved against the force of the spring 23 to cause its entire surface to engage with the heel portion of the sole. V

\While it is preferred to employ the specific construction and arrangement of parts shown and described, itwill be understood that 'this construction and arrangement is not essential except so far as specified in the claims, and' may be changed v or modified 'without departing from the broader features of the invention.

The invention having been described, what is claimed is 2- 1. A sole pressing machine, having, in l combination, a pair of coperating pressing forms, a gage for positioning the sole reiative to the forms, a gripping member, and mechanism for actuating the gripping member to cause the sole engaging surface of the member to move towardthe gage as the member is moved'into a clamping position; i

2. A` sole pressing machine, having, in' combination, a supporting form,a coperating pressing form 'having a recess formed in the 'face,` a plate engaging with substantially the entire heel portion of. the sole and having a sole 'engaging' surface conforming` exactly with the recess in the pressing form, and mechanisn for a'ctuating the piate 'to c'lamp the 'sole .prior to .the relative movenent of the forms into pressing position.

3. A sole. pressing machine, having' in combination, apair of coperating forms, a gage for positioning the soie relative to the forms, a gripping d'evice independentof the gage and having asole engaging surface normally positioned at an angle to the cooperata ing portion of the sole supportingform, and

mechanism' for a'ctuating the gripping de- Vice' to cause the sole engaging surface to be turnedinto a position parallel to the surface of the' formupon a movement of the gripper into clampingposition. V z

4:; A soie pressingmachine, hav1ng, '1n combination, apair of coperating forms, a gage for positioning the sole relative to the forns, an arm, a gripping member pivotally, connected to the arm, and 'a' spring` normally retaining the sole engaging surface 'of the member' at an angle to 'the sole withthe portion` ofthe surface adjacent to,

the gage nearest to the sole.
